The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact. (CVE-2017-11176)

Impact

An attacker may be able to exploit this vulnerability to cause a denial-of-service (DoS) or other unspecified impact.
